Focus tree is gimmicky and easy to counter. Combat is still the most powerful pvp spec. If you cannot kill sentinels as a vanguard, then you lack the skill required. Period. Reducing the range on thermal detonator and inc missle is not a nerf If you are competent with the class. A guy on my ranked team is 100 valor rank 2140 pyro Powertech, and he still outworks and outplays other players. Especially focus spec maras. Stop blaming BW on your shortcomings as a player.
